Drains & sewer services in Pittsburgh
Drain cleaning
UrgentIf one fixture is slow, the clog is usually in that fixture's branch line. If several drains back up at once, or the basement floor drain fills when you run the washer, the main sewer line is blocked and needs a larger cable or a jetter.
Hydro jetting
Hydro jetting cleans the full width of a drain pipe with high-pressure water, washing out grease, scale and fine roots that a cable only punches a hole through. It works best on sound pipe and is usually done after a camera inspection confirms the pipe can take it.
Sewer camera inspection in Pittsburgh
A sewer camera inspection runs a waterproof camera through the line from your house to the city main and records what it finds: roots, cracks, sags, offset joints or collapsed pipe. It's the best way to decide between cleaning, spot repair and replacement.
Sewer line repair in Pittsburgh
UrgentA damaged sewer line can be fixed with a spot repair, a trenchless liner, pipe bursting or an open-trench replacement. Which one fits depends on what the camera shows, how deep the pipe is, and what's on top of it, such as a driveway, trees or landscaping.
Local conditions
Drains & sewer in Pittsburgh: what's different
Pittsburgh's steep lots and old clay laterals lead to cracked, root-filled lines. Runoff during heavy rain can overwhelm older combined sewers.
In Allegheny County, plumbing permits and inspections come from the Allegheny County Health Department's plumbing program.
Laterals on hillside lots can be long and steep, which makes repairs costly, so a camera inspection first shows exactly where the damage is. Trenchless lining is often used to avoid digging on slopes. Pittsburgh Water maintains the public sewer, and the lateral belongs to the owner.
